It features a 47\/64 inch (0.7344 inches) diameter, a 135-degree notched split point for self-centering starts, and a spiral flute geometry with a 6xD flute-to-diameter ratio. The cobalt tool material provides heat and wear resistance beyond standard high-speed steel, making it suitable for hard and abrasive materials. The straight shank and web-thinned, tapered web configuration reduce thrust and improve chip evacuation. This bit is typically installed by machinists, maintenance technicians, and metalworking tradespeople using a drill press, mill, or hand drill with a keyed chuck.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for use across a broad range of materials including alloy steel, carbon steel, stainless steel, hardened steel, cast iron, malleable iron, aluminum, aluminum alloy, brass, bronze, high strength bronze, copper, nickel, nickel alloy, magnesium, magnesium alloy, cermet, graphite, and reinforced plastic materials. The taper length body gives more reach than a jobber bit while maintaining rigidity, making it a practical choice for through-hole drilling in structural components, fabrication work, and maintenance repair operations where standard-length bits fall short.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for superior heat resistance and extended tool life in hard metals\u003c\/li\u003e\n  \u003cli\u003e135-degree notched split point enables self-centering entry without a center punch on most materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces drilling thrust and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with 6xD ratio promotes efficient chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eStraight shank at 47\/64 inch diameter fits standard keyed and keyless chucks\u003c\/li\u003e\n  \u003cli\u003eANSI-standard geometry for consistent dimensional interchangeability\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; coated finish for added surface protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the PRECISION TWIST DRILL M51CO series.

De-energize and lock out any machine tool before changing or inspecting bits. Use appropriate cutting fluid or coolant when drilling stainless steel, hardened steel, or other work-hardening alloys to preserve edge life. Follow applicable ANSI B11 machine tool safety standards and shop-specific PPE requirements when operating drill presses or milling equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 47\/64\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.7344 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched (Self-Centering)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5-7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight, Non-Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 47\/64 inch (0.7344 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy-Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M51CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5996312\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51712088637746,"sku":"5996312","price":169.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4384cf74ba866935d20ba7e6fe2e223a_c8afc3fe-ac9c-44c1-95af-77d3c52146ab.jpg?v=1788483607","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996312-taper-length-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
